Hello, could somebody please explain to me why in 4 of these solutions, the angular momentum final term about point p is mVfR + Icmω ? It is in huge attached solutions my teacher posted.

Thank you very much in advance

Here is the problem in case you are interested of Horne context.

4. A solid ball of radius are initially slides without rotating on a horizontal surface with a variable coefficient of friction. If the initial speed is Vo, find the speed when the ball begins to roll without slipping. Also find the energy lost due to friction

Come on.. I know you smart cats know what this angular momentum term is all about. PLEASE I AM DESPERATE.
 
Sorry my iPad edited this very poorly...4. A solid ball of radius R initially slides without rotating on a horizontal surface with a variable coefficient of friction. If the initial speed is Vo, find the speed when the ball begins to roll without slipping. Also find the energy lost due to friction
 
I understand the angular momentum is conserved but I don't understand the final term in the angular momentum. I can't find out anything, it's bewildering me.
